Abstract:

To study the pilot-scale purification process and bacteriostatic effect of hypocrellin during the pilot-scale production, we extracted hypocrellin using different solvents and extraction methods. Then, we investigated the purification effects of the hypocrellin using salting-out, physical cooling, and ultrafiltration methods. The results showed that the amount of hypocrellin extracted using the jet pulverization method could reach up to 21.4 mg/g, and its density could exceed 90% after its purification via ultrafiltration. The analysis of the bacteriostatic activity of hypocrellin showed that it had good thermal stability and inhibitory effects against Escherichia coli and Candida albicans. We found that hypocrellin has natural antibacterial properties and good thermal stability, is easy to extract and purify, and can be used as a bacteriostatic drug in medicine and other applications.

Key words: hypocrellin, extraction, purification, stability, bacteriostatic activity
